Diagram of lake basin delineation. (a) shows the determination of inlets and outlets of the lake based on flow direction calculated by the D8 algorithm. (b) shows the upstream drainage areas merged by all the sub-basins that flow into the lake. (c) are the basin delineation results of two example lakes: the overflow lake (ID46) and the terminal lake (ID93).
